Matthew 27:4-8

Saying, I have sinned in that I have betrayed the innocent blood. And they said, What is that to us? see thou to that.

And he cast down the pieces of silver in the temple, and departed, and went and hanged himself.

And the chief priests took the silver pieces, and said, It is not lawful for to put them into the treasury, because it is the price of blood.

And they took counsel, and bought with them the potter’s field, to bury strangers in.

Wherefore that field was called, The field of blood, unto this day.
